Subject: [PATCH v3 0/7] Fixups for s2idle on various Rembrandt laptops

It was reported that an ASUS Rembrandt laptop has problems with seemingly
unrelated ACPI events after resuming from s2idle. Debugging the issue
proved it's because ASUS has ASL that is only called when using the
Microsoft GUID, not the AMD GUID.

This is a bug from ASUS firmware but this series reworks the s2idle
handling for AMD to allow accounting for this in a quirk.

Additionally as this is a problem that may pop up again on other models
add a module parameter that can be used to try the Microsoft GUID on a
given system.

This module parameter intentionally applies to both Intel and AMD systems
as the same problem could potentially exist on Intel systems that support
both the Intel GUID or the Microsoft GUID.

v2->v3:
 * Add more systems
v1->v2:
 * Add two more systems that are reported to be helped by this series.

Mario Limonciello (7):
  acpi/x86: s2idle: Move _HID handling for AMD systems into structures
  acpi/x86: s2idle: If a new AMD _HID is missing assume Rembrandt
  acpi/x86: s2idle: Add module parameter to prefer Microsoft GUID
  acpi/x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE
  acpi/x86: s2idle: Add a quirk for ASUS ROG Zephyrus G14
  acpi/x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7
  acpi/x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC. ROG Flow X13
